I've actually tried this, after watching that video. I am not sure if it actually worked or if it was a placebo, but in the end I found it was way more convenient and cleaner to just use snus the way it's usually used.
You can try it with a cartomizer also, just take out the polyfill, push aside the air tube and stuff a portion in there. I don't think anything larger than a mini will fit. Then drip in vg or e-liquid on top of the snus "polyfill" and let it soak. (it always leaked through though, so either snus makes a poor polyfill or this thing is better done with cartridges.) I got vapor and I felt like it was working, but again, discontinued the experiment because I was getting vg all over the place and that stuff is a mess. I used a typical 808 cig-style device/carto and General Mini Mint portions.
